Bottom Line: In contrast, acerola juice and Vitamin C intake ameliorated the weight gain, reducing the TAG levels and increasing the IL-10/TNF-α ratio in adipose tissue.In addition, acerola juice intake led to reductions both in the level of phosphorylated JNK and to increases in the phosphorylation of IκBα and HSLser660 in adipose tissue.Taken together, these results suggest that acerola juice reduces low-grade inflammation and ameliorates obesity-associated defects in the lipolytic processes.

ABSTRACT

Background: Obesity has been studied as a metabolic and an inflammatory disease and is characterized by increases in the production of pro-inflammatory adipokines in the adipose tissue.To elucidate the effects of natural dietary components on the inflammatory and metabolic consequences of obesity, we examined the effects of unripe, ripe and industrial acerola juice (Malpighia emarginata DC.) on the relevant inflammatory and lipolysis proteins in the adipose tissue of mice with cafeteria diet-induced obesity.

Materials/methods: Two groups of male Swiss mice were fed on a standard diet (STA) or a cafeteria diet (CAF) for 13 weeks. Afterwards, the CAF-fed animals were divided into five subgroups, each of which received a different supplement for one further month (water, unripe acerola juice, ripe acerola juice, industrial acerola juice, or vitamin C) by gavage. Enzyme-linked immunosorbent assays, Western blotting, a colorimetric method and histology were utilized to assess the observed data.

Results: The CAF water (control obese) group showed a significant increase in their adiposity indices and triacylglycerol levels, in addition to a reduced IL-10/TNF-α ratio in the adipose tissue, compared with the control lean group. In contrast, acerola juice and Vitamin C intake ameliorated the weight gain, reducing the TAG levels and increasing the IL-10/TNF-α ratio in adipose tissue. In addition, acerola juice intake led to reductions both in the level of phosphorylated JNK and to increases in the phosphorylation of IκBα and HSLser660 in adipose tissue.

Conclusions: Taken together, these results suggest that acerola juice reduces low-grade inflammation and ameliorates obesity-associated defects in the lipolytic processes.

Effects of cafeteria diet on inflammatory parameters in epididymal adipose tissue. TNF-α (pg/μg protein-1) (a); IL-10 (pg/ug protein-1) (b); and IL-10/TNF-α ratio (c) of mice fed the standard diet (STA), the cafeteria diet with distilled water (CAF + WD), the cafeteria diet with vitamin C (CAF + Vit C), the cafeteria diet with industrial acerola juice (CAF + IND), the cafeteria diet with the juice of unripe acerolas (CAF + UNR) or the cafeteria diet with the juice of ripe acerolas (CAF + RIP). The results are expressed as means ± SEM (n = 6 per group). $p < 0.05 versus standard diet; *p < 0.05 versus the cafeteria diet with distilled water; #p < 0.05 versus the cafeteria diet with vitamin C.

Figure 2: Effects of cafeteria diet on inflammatory parameters in epididymal adipose tissue. TNF-α (pg/μg protein-1) (a); IL-10 (pg/ug protein-1) (b); and IL-10/TNF-α ratio (c) of mice fed the standard diet (STA), the cafeteria diet with distilled water (CAF + WD), the cafeteria diet with vitamin C (CAF + Vit C), the cafeteria diet with industrial acerola juice (CAF + IND), the cafeteria diet with the juice of unripe acerolas (CAF + UNR) or the cafeteria diet with the juice of ripe acerolas (CAF + RIP). The results are expressed as means ± SEM (n = 6 per group). $p < 0.05 versus standard diet; *p < 0.05 versus the cafeteria diet with distilled water; #p < 0.05 versus the cafeteria diet with vitamin C.

Mentions: We observed that the TNF-α levels were increased in the CAF + WD group when compared with the STA group (p < 0.05), although the TNF-α levels were reduced in all of the treated groups when compared with the CAF + WD group (p < 0.05). There was no difference in the TNF-α levels among the treatment groups (p > 0.05; Figure 2a). When the IL-10 levels (an important anti-inflammatory cytokine) were analyzed, we observed that the IL-10 levels were unchanged between the CAF + WD and STA groups (p > 0.05), even though the IL-10 levels were reduced in the CAF + Vit C group when compared with the CAF + WD group (p < 0.05). In addition, the IL-10 levels were higher in the CAF + IND group than in the CAF + Vit C group (p < 0.05; Figure 2b). We observed that the IL-10/TNF-α ratio was reduced in the CAF + WD group when compared with the standard diet group (p < 0.05). However, the IL-10/TNF-α ratio in the CAF + Vit C, CAF + IND, CAF + UNR, and CAF + RIP groups was increased when compared with the CAF + WD group (p < 0.05; Figure 2c).
